BUNG.

SPECIFICATION forming part of Letters Patent No. 778,974, dated January3, 1905.

Application filed January 15, 1902. Serial No. 89,871.

To (all whom/ 7115 may concern Be it known that LGnoReE l/V. J ACKSON, acitizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Bungs, of which the following is a specification.

My invention comprises a novel bung for casks, barrels, or the like,together with a compressible packing-ring therefor.

It further consists of novel features of construction, all as will behereinafter fully set forth.

Figure 1 represents in vertical section a bung embodying my invention.Fig. 2 represents a similar view of a packing-ring before its insertionin the bung.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a bush having an annular wall 2,provided exteriorly with a thread 3, adapted to engage with thebung-hole of a cask. At the upper end of the wall 2 is a horizontalflange 4 of ordinary construction. At the lower end of the wall 2 is anannular inwardly-projecting flange 5. As shown, the interior of the wall2 has a substantially vertical portion 6 at its lower end and a flaringportion 7 thereabove. lVithin the bush 1 is seated a hung 8, having atapered wall 9, surmounted by a knob or handle 10 and having at itslower end an outwardly-extending flange 11, shown as of a diametersubstantially equal to that of the cylindric portion 6 of the wall 2,although the size of the flange is obviously non-essential. An annularpacking-ring 12 is shown as having both its inner and outer wallssomewhat tapering. This ring is made of a compressible absorbentmaterial, as wood or the like, and is of a thickness somewhat greaterthan the space between the walls of the bush and the bung.

The operation is as follows: The bush I having been screwed into thebung-hole of the barrel, the bung 8 is seated therein with its flange 11resting on the flange 5 of the bush. The packing-ring 12 is thenforcibly driven into the space between the wall 9 of the bung and theportion 6 of the wall 2 of the bush. 5 By reason of its compression itwill form a seal to prevent any leakage from the barrel or cask, theefficiency of the seal being increased by the swelling of the ring dueto its absorption of any liquid which may seep there- 5 5 into.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A barrel-stopper comprising a bush having the inner face of itsannular wall substantially vertical at its lower end and flaringoutwardly thereabove and having an inwardly-extending flange at itslower end, a vertically-insertible bung having a body of less-diameter 5than said bush-wall and a flange at its lower end substantially fillingsaid bush and a compressible packing-ring of absorbent material of athickness normally greater than the space between said bung-body andsaid bush-wall, said packing-ring forming the means for retaining saidbung in said bush and being removable with said bung.

2. A barrel-stopper,comprising a bush, having the inner face of itsannular wall approxi- 7 5 mately vertical at its lower end and having aninwardly-extending flange at the foot of said wall, avertically-insertible bung having a body of less diameter than saidbush-wall and having a flange at its lower end adapted to seat upon theflange in said bush, a compressible packing-ring of absorbent materialof a thickness normally greater than the space between said bung-bodyand said bush-wall, said packing-ring forming the means for retainingsaid 5 bung in said bush and being removable with said bung.
